1. Field of the Invention
Embodiments of the present disclosure relate to antennas, and particularly to a solid antenna.
2. Description of Related Art
With the development of wireless communication technologies, wireless communication devices, such as mobile phones, notebook computers, and personal digital assistants (PDAs), are now in widespread use. When combined with communication modules, wireless communication devices can connect to local area networks (LAN), transceive E-mail, and download real time information, such as news and stock quotes.
Antennas are necessary components in wireless communication devices for radiating electromagnetic signals. In order to obtain compact wireless communication devices, the antennas associated therewith are correspondingly required to be small in size, at the same time maintaining adequate performance standards.
An exemplary embodiment of the present disclosure provides a solid antenna. The solid antenna is positioned on a substrate, and comprises a feeding portion and a radiating portion. The feeding portion is configured for feeding electromagnetic signals. The radiating portion is configured for transceiving the electromagnetic signals, and comprises a first radiator, a second radiator, a third radiator, a fourth radiator, a first connecting section, and a second connecting section. The first radiator is positioned on a first plane, and electrically connects to the feeding portion. The first radiator comprises a first inverted-U-shaped radiating section. The second radiator is positioned on the first plane, and comprises a second inverted-U-shaped radiating section. The third radiator is U-shaped, and positioned on a second plane. The second plane is perpendicularly to the first plane. The first connecting section electrically connects the first radiator to the third radiator. The second connecting section electrically connects the second radiator to the third radiator. The fourth radiator electrically connects to the second radiator. The first connecting section, the second connecting section, and the fourth radiator comprise one radiating section positioned on a third plane.
Another exemplary embodiment of the present disclosure provides a solid antenna. The solid antenna comprises a feeding portion and a radiating portion. The feeding portion is configured for feeding electromagnetic signals. The radiating portion comprises a plurality of radiating sections connected one-by-one to collectively form a helical-shaped configuration. A first rectangular-shaped radiating section positioned in the periphery of the helical-shaped configuration of the radiating portion electrically connects to the feeding portion, and in the center of the helical-shaped configuration of the radiating portion is a free section. Some radiating sections adjacent to the feeding portion are positioned on a first plane, and other radiating sections apart from the feeding portion are positioned on a second plane.
Other advantages and novel features of the present disclosure will become more apparent from the following detailed description of certain inventive embodiments when taken in conjunction with the accompanying drawings, in which:
The feeding portion 20 feeds electromagnetic signals to the solid antenna 10. In one embodiment, the feeding portion 20 may be rectangularly-shaped, and perpendicularly connects to the substrate 50.
The radiating portion 40 electronically connects to the feeding portion 20 and transceives electromagnetic signals. The radiating portion 40 includes a plurality of radiating sections connected one-by-one to collectively form a helical-shaped configuration. A first rectangular-shaped radiating section 110 is positioned in the periphery of the helical-shaped configuration of the radiating portion 40, and electrically connects to the feeding portion 20. In the center of the helical-shaped configuration of the radiating portion 40 is a free section 410. In one embodiment, the radiating sections of the radiating portion 40 include a first radiator 100, a second radiator 200, a third radiator 300, a fourth radiator 400, a first connecting section 510, and a second connecting section 520.
It may be understood that the first radiator 100, the second radiator 200, the third radiator 300, the fourth radiator 400, the first connecting section 510, and the second connecting section 520 of the radiating portion 40 may be positioned on different planes of the substrate 40. The different planes on the substrate may be angled differently according to the Z and Y-axis of a coordinate axis-system.
As shown in
The second radiator 200 is also positioned on the first plane, and includes a first S-shaped radiating section 210, a second inverted-U-shaped radiating section 220, and a second S-shaped radiating section 230, which are connected to each other one-by-one in sequence. In one embodiment, the second inverted-U-shaped radiating section 220 has substantially the same shape and opening direction as the first inverted-U-shaped radiating section 120.

In one embodiment, the third radiator 300 comprises an opening direction that is opposite to an opening direction of first inverted-U-shaped radiating section 120 and an opening direction of the second inverted-U-shaped radiating section 220. The size of the opening of the third radiator 300 is bigger than that of the opening of the first inverted-U-shaped radiating section 120 and of the opening of the second inverted-U-shaped radiating section 220.
The first connecting section 510 connects the first radiator 100 to the third radiator 300.
